They are easy to program and I believe readily available from W4TV.
Yes, both microHAM Stack Switch (stack switching/matching for 2 or
3 antennas) and Stack Max (Stack Switch controller) are available
from stock at www.microHAM-USA.com.
I currently need to be able to control 7 relays in 7 programmable
different combinations (all involving either 1, 5, or 6 of the relays
to be energized at a time, per the K3LR article from the 90's).
Steve, you do not say which article so I can't comment directly to
that controller. However, Stack Max does contain settings for both
the N4TZ and OM2KW stack designs (4 antennas - 8 relay outputs) if
one of them fits your requirements. In addition, there is support
for several other "commercial" 2 and 3 antenna stacking units.

I really dislike rotatary switches too. I use MicroHAM Stacks Max with
my Array Solution two and three Yagi StackMatches
http://www.microham.com/contents/en-us/d84.html They are easy to
program and I believe readily available from W4TV. DX Engineering may
have a K3LR type switch with more buttons soon.

Hey guys,
After a recent lightning event I find that my 20M 3-high stack
controller got zapped. This is an IC based homebrew design that a friend
made for me in the 90's.
I'll be able to swap in the 10M controller as a temporary fix, but going
forward am wondering if there is an easy commercial replacement
available, maybe with a bit more flexibility (more relay outputs).
I currently need to be able to control 7 relays in 7 programmable
different combinations (all involving either 1, 5, or 6 of the relays to
be energized at a time, per the K3LR article from the 90's).
My current control boxes have 7 buttons each of which can direct access
the 7 relay combos. I much prefer this over any rotary control switch.
Anyway, I know this is a simple task for a little Arduino box and relay
controller - is there anything out there that is (almost) ready to go?
Thanks,
-Steve K8LX
